## What it does

A compositional skill that weaves data-driven content, dialogue, and persistence into a cohesive system. Inside are patterns for derived stats (recomputed from base attributes to prevent corruption), XP curves and leveling, quest state machines, inventory with equipment modifiers, and versioned save formats.

The core loop runs: explore → encounter (fight, talk, solve) → earn rewards (XP, loot, story) → grow (level, gear, unlock) → tackle harder content. The skill walks through common pitfalls: mutating base stats instead of layering modifiers, storing derived stats as ground truth, unchecked numerical growth, and stacked buffs that multiply instead of sum.

Built around Godot and Unity patterns; designed to compose with other skills for dialogue (`dialogue-systems`), saves (`save-systems`), content data (`godot-resources`, `unity-scriptableobjects`), enemy AI (`game-ai`), and UI (`game-ui-ux`).

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill rpg -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/rpg/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rpg/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill rpg -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/rpg/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill rpg -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/rpg/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install gamedev-skills/awesome-gamedev-agent-skills rpg
```

2. **Manually: put the files in place**
- File: `.github/skills/rpg/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill rpg -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/gamedev-skills/awesome-gamedev-agent-skills --path skills/genres/rpg
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/rpg/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill rpg -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/gamedev-skills/awesome-gamedev-agent-skills/tree/HEAD/skills/genres/rpg/SKILL.md

## When to use it
- design an XP curve that paces power progression
- build a damage formula with predictable scaling
- structure inventory and equipment to layer stat modifiers cleanly
- implement a quest state machine that branches on player choices
- persist character progress with save versioning and migration

## Example prompts
- Show me a pattern where base attributes feed derived combat stats without storing them as truth
- What XP curve shape gives fast early levels but slows down at the end?
- How do I save mid-quest state so a reload doesn't lose progress?

# RPG

A playbook for role-playing games — stats and progression, inventory/equipment, quests,
dialogue, and combat. This is a **compositional** skill: it ties data-driven content,
dialogue, and saving together. It does not re-teach those primitives; it defines the systems
that make growth and choice feel meaningful, and points to the skills that implement each.

## When to use

- Use when building an RPG/JRPG/action-RPG: the player has **stats that grow**, an
  **inventory**, **quests**, **dialogue**, and persistent progress.
- Use when designing a leveling curve, a damage formula, an inventory/equipment model, or a
  quest state machine.

**When *not* to use:** permadeath dungeon runs with no persistent character → `roguelike`.
Pure conversation/branching story → `visual-novel`. Open-world needs/crafting/base-building →
`survival-crafting`. For the dialogue engine itself, use `dialogue-systems`.

## Core loop

**Explore → encounter (fight / talk / solve) → earn rewards (XP, loot, story) → grow
(level up, gear up, unlock) → take on harder content.** The fantasy is *getting stronger and
shaping who your character is*; every system should feed that growth-and-choice loop.

## Must-have systems

1. **Stats + leveling** — base attributes, derived combat stats, XP curve, level-up gains.
2. **Inventory + equipment** — data-defined items, stacking, slots, stat modifiers.
3. **Combat** — turn-based or action; damage formula, status effects, win/loss.
4. **Quests** — objectives, state machine (available→active→complete→turned-in), rewards.
5. **Dialogue** — branching lines, conditions on game state, choices that matter.
6. **Save/load** — persist character, inventory, quest progress, world flags, with versioning.
7. **Economy + progression gating** — gold/shops; gate power behind level/quest/region.
8. **UI** — HUD, inventory, quest log, dialogue box, character sheet.

## Design knobs

| Knob | Effect | Notes |
|------|--------|-------|
| XP curve shape | pacing of power | Fast early, slow late (see refs). |
| Stat→derived scaling | build diversity | One attribute shouldn't dominate. |
| Damage formula | tactical feel | Subtractive vs. ratio mitigation (refs). |
| Random variance / crit | swinginess | ±10% and ~1.5× crit are safe defaults. |
| Drop rates / economy | reward cadence | Avoid trivializing shops with loot. |
